Example for Command Settings

This section describes how to set command strings for Attribute and provides a setting example.
• As the data transmitted from the PLC to the Sensor Controller, set a command string equivalent to a
command for the non-procedure protocol. Add NULL (0x00) at the end of the string. No line feed
code is required. The size of the transmitted data includes the NULL (0x00) at the end of the string.
• As the data received by the PLC from the Sensor Controller, return string data equivalent to the re-
ceived string of a command for the non-procedure protocol. NULL (0xll) is inserted into the delimiter
part in the received string. The size of the received data includes the NULL (0x00) at the end of the
string.
Examle: When getting the number (0) of the currently used scene:
(Transmitted data: 2 bytes) 0x53 ('S') 0x00
↓
(Received data: 5 bytes) 0x30('0') 0x00 0x4f('O') 0x4b('K') 0x00
